Notice the following result when I submit blank :title and :description fields
The validations are in the controller:
class Question < ActiveRecord::Base
validates_presence_of :title
validates_presence_of :description
And, the form is generated with those names:
-form_for(@question) do |f|
= f.error_messages
= f.label :title
= f.text_field :title, :size => 50, :onchange => remote_function(:url => {:action => :display_tag_suggestions}, :with => 'Form.Element.serialize(this)')
#suggestions
= f.label :description
= f.text_area :description
...
But, for some reason, only :title gets wrapped in the error div tags:
<form action="/questions" class="new_question" id="new_question" method="post">
<div style="margin:0;padding:0"><input name="authenticity_token" type="hidden" value="6HQaiu1D0gBQcKw2pLeZP6Jvn0FSClPD5Sk9HwegzPg=" /></div>
<div class="errorExplanation" id="errorExplanation">
<h2>2 errors prohibited this question from being saved</h2>
<p>There were problems with the following fields:</p>
<ul>
<li>Title can't be blank</li>
<li>Description can't be blank</li>
</ul>
</div>
<label for="question_title">Title</label>
<div class="fieldWithErrors"><input id="question_title" name="question[title]" onchange="new Ajax.Request('/questions/display_tag_suggestions', {asynchronous:true, evalScripts:true, parameters:Form.Element.serialize(this) + '&authenticity_token=' + encodeURIComponent('6HQaiu1D0gBQcKw2pLeZP6Jvn0FSClPD5Sk9HwegzPg=')})" size="50" type="text" value="" /></div>
<label for="question_description">Description</label>
<textarea cols="40" id="question_description" name="question[description]" rows="20"></textarea>
...
I don't think that behavior is expected. The problem most people have is that it's wrapping things with divs, which won't display properly. My problem is that fields aren't being wrapped with divs to begin with!
I haven't made any (conscious) changes to how errors are handled, so I'm not sure why it's not working properly.
